Commonly applied drug forms tend to leave the vagina when the patient assumes an upright position. Permanent contact of the drug form with the vaginal mucosa during daily activities of the patient is an indispensable condition for 24-hour therapy. This condition may be fulfilled by drug forms with high ability to adhere to vaginal mucosa. The investigations demonstrated that the thermosensitive polymer - poloxamer 407 increases significantly the adhesive properties of hydrophilic gels, but at the same time it increases their pH. The use of pectin resulted in a decrease of the pH. The addition of glycerol or 1,2-propylene glycol caused further decrease of the pH. Rheological investigations demonstrated positive pharmaceutical properties of the investigated preparations. The obtained parameters gels should provide positive application effects. The investigations revealed that it is possible to obtain gels with high adhesion properties to vaginal mucous membrane.
